A ruby and diamond ring, by Gimel

A ruby and diamond ring, by Gimel

A 9.50 carat Burma ruby and diamond ring, by GimelEstimate HK6,400,000 – HK$8,500,000 ($800,000-1,100,000). Photo Christie's Image Ltd 2015

Set with a cushion-shaped ruby, within a brilliant-cut diamond surround, extending to the half-hoop, mounted in 18k gold, ring size 5¼. Signed and with maker's mark for Gimel 

Accompanied by report no. 79646 dated 30 March 2015 from the SSEF Swiss Gemmological Institute stating that the approximately 9.50 carat ruby is of Burma (Myanmar) origin, with no indications of heating; also accompanied by an appendix stating that the ruby possesses extraordinary characteristics and merits a special mention and appreciation. The ruby exhibits a remarkable size combined with an attractive colour and a fine purity. The few inclusions found by microscopic inspection represent the hallmarks of rubies from the classical ruby mines in the Mogok valley in Burma (Myanmar), well known for its wealth in gems since historic times. Its saturated red colour is due to a combination of well-balanced trace elements in this gemstone, characteristic for the finest rubies from Mogok. In addition, the ruby has been spared exposure to heat treatment and its clarity and colour are thus entirely natural. A natural ruby from Burma of this size and quality is rare and exceptional.
